Omni mic pair in a single blimp

January 8, 2021

I’m a fan of omni SDC pairs for outside recording. For music I will often use these in Rycote Baby Ball Gags mounted on a stereo bar, itself on a substantial stand (usually the Manfrotto 1004BAC). But where I want something more portable and more windproof, I mount the two omni mics end-to-end inside a single windshield – the Rode blimp Mk1. Joining the two mics end-to-end is easy with a rewired and drilled female-to-female xlr coupler (well, actually, the female-to-female XLR connector is actually not off-the-peg, but made up of three items: two Neutrik NM3FXI and one Neutrik KM. Neutrik’s own female-to-female XLR connector doesn’t unscrew). This places the micsĀ  (a pair of Rode NT55 mics with the excellent NT45-O omni capsules) at a 360mm spacing, which renders a good stereo image and is exactly the ideal length for the Rode blimp (i.e. the same length as the straight part of the blimp). Being pure pressure omni mics there is, of course, no phase issue arising from the fact that they are pointing different directions.

So the end result: a simple robust set up, less fiddly and more portable than common field-recording set-ups for ORTF pairs etc. and – being all enclosed – more windproof. It’s not something I have seen or read about, but I imagine – or hope – others are doing the same.

And here’s a detail of the easily modified connector: just drill a couple of holes for the cables.
